@cats200 - I meant Jet Airways and Indian Airlines are a more secure company compared to Spice in terms of company closing down and other such economic related issues. Otherwise, Spice pays a lot more than Indian Airlines, at least for the batch that got selected in Mid-2007. After that, the salary cap has been reduced for F/O's. I'm guessing they're the F/O's that are planning on leaving/left Spicejet.
